Hi,

I have added JFR events for the parallel phases of G1.

This change adds JFR events for most values of the enumeration 
GCParPhases. I have also added a test case (TestG1ParallelPhases.java).

This is a rebase/rework of a previous post I did 31th of January that 
never got pushed.

Enhancement:
https://bugs.openjdk.java.net/browse/JDK-8196341

Webrev:
http://cr.openjdk.java.net/~lkorinth/8196341/00/

Testing:
- mach5 hs-tier1,hs-tier2,hs-tier3
- brief visual inspection of result in JMC
- new test TestG1ParallelPhases.java (100 runs)

Thanks,
Leo
